Temper tantrum?

I haven't posted since April!! That should give you an idea of all that's been going on. Well baby is now 8-months old and I believe he had an actual temper tantrum today. Is it possible for an 8-month old to do that? He was upset today because I wouldn't pick him up. At 22.5 lbs, it's become quite the task to carry this kid. Alas, he continued until he wore himself out. Kids I tell you.
